Abstract
Description
- The present invention relates to a flexible envelope for protecting medical appliances against contamination, particularly as when used for the administration, draining or withdrawal of substances.
- Medical appliances used for the administration to patients and the draining or withdrawal from patients of substances such as fluids, for therapeutic or diagnostic purposes, are at serious risk of contamination by microbes, viruses, bacteria, etc. present in the environment. These contaminating agents can easily be introduced into the abovementioned appliances, e.g. through the tube connections, taps, valves and so forth, with which such appliances are provided, and cause serious infections in the patient using said appliances.
- Current hospital practice is to wrap such medical appliances (or parts thereof) in pieces of gauze or bandages impregnated with sterilizing or anticontaminating agents and sometimes to enclose the whole in an impermeable protective film for safety. But this procedure is laborious, impedes quick access to the protected appliance and is not even reliable from the point of view of asepsis; it is therefore often neglected.
EP-A-0,311,532 discloses a flexible protective envelope of the specified type comprising: - a) a backing consisting of a strong, flexible, elastic, impermeable film;
- b) a layer of spongy, absorbent material, smaller than the backing and attached centrally thereto;
- c) lateral and transverse closure means which have self-retaining hooks and loops (of the type known as "Velcro", registered trademark) with which to close the envelope onto itself, the appliance being held inside, after the envelope has been folded along its central transverse axis.
- The layer of spongy material is attached to the backing with hot-melt adhesive. The lateral and transverse closure means are also fixed to the backing with hot-melt adhesive.
- However, this flexible protective wrapping has the following principal drawbacks:
- the layer of spongy material which is impregnated during use with sterilizing or anti-contaminating agents in a liquid or pasty state readily releases said agents, which escape through the lateral edges of the envelope and are then lost and get on to other appliances, the operators and the patient;
- the adhesive used to attach the spongy layer and the lateral and transverse closure means to the backing is subject to the chemical action of the sterilizing and anti-contaminating agents, and to the physical action of repeated opening forces, and consequently its properties soon fail and said parts become detached from the backing;
- the so-called "Velcro"-type closure means when closed upon each other provide no protective barrier against contaminating agents, which therefore get inside the closed envelope through the perimeter areas.
- The above drawbacks are the starting point of this invention, the object of which is to eliminate the same.
- The main object of the present invention is therefore to provide a flexible envelope for protecting medical appliances against contamination, particularly as when used for the administration, draining or withdrawal of substances, that will guarantee anti-bacterial, anti-viral and anti-microbial protection against contamination rising up all kinds of appliances and systems in medical, pharmaceutical and non-drug uses as used for the administration to patients and the sampling and withdrawal from patients of substances (organic or otherwise), e.g. using infusion or withdrawal techniques.
- Another object is to provide a protective envelope as specified that will safely hold in its interior the sterilizing and anti-contaminating agents with which it is impregnated; that will not be subject to detachment of parts during use; and that will provide a closure around its external perimeter forming a secure barrier against the ingress of contaminating agents.
- A further object is to provide a protective envelope as indicated that will be simple in structure, safe, convenient and reliable in use and simple to manufacture industrially.
- To achieve these objects, the present invention provides a flexible envelope for protecting medical appliances against contamination, particularly as when used for the administration, draining or withdrawal of substances, the essential features of which are the subject matter of the main claim, which should be regarded as incorporated here in its entirety.
- Further advantageous features are described in the subordinate claims, which should likewise be regarded as incorporated here in their entirety.
- The present invention is described in detail below with reference to the accompanying illustrative drawings in which:
- Fig. 1 is a plan view of the flexible protective envelope according to the model, opened out and showing its inner side;
- Figures 2 and 3 are partial sections on an enlarged scale taken through lines II-II and III-III, respectively, shown in Fig. 1;
- Fig. 4 is a schematic perspective view illustrating the flexible protective envelope according to the model wrapped partly round a connection with two taps for flexible tubes, when the envelope is about to be folded over upon itself;
- Fig. 5 is a view similar to that shown in Fig. 4 but with the flexible protective envelope folded fully over upon itself and closed to protect said connection;
- Fig. 6 is a view similar to that shown in Fig. 5 but showing the envelope with the connection inside it suspended from hanging means;
- Fig. 7 is a view similar to that shown in Fig. 1 but illustrating a small version of the envelope according to the present invention.
- In the drawings the numeral 10 (Fig. 1) denotes the flexible protective envelope as whole according to the present invention.
- The
envelope 10 essentially comprises the following components (see in particular Figs. 2 and 3): - a highly impermeable and strong
flexible backing sheet 11 consisting of, for example, a flexible polyvinyl chloride (PVC) film having a thickness of 100-150 µm and a square outline, like the embodiment shown in Figures 1-6; - a layer of
padding 12 made of a highly absorbent flexible spongy synthetic material, for example a layer of a flexible expanded polyurethane material such as Moltopren (registered trademark) having a uniform thickness of 3 mm, which entirely covers one side of saidbacking sheet 11 and is attached to it by a continuous weld line (at 13), e.g. by hot welding or electrical welding; - a permeable flexible nonwoven covering 14 attached on top of said layer of
padding 12 by a continuous weld line (at 15), e.g. by hot welding or electrical welding, and is, for example, cross processed, 20 µm, which components form a pad, for example a quadrilateral pad, in the form of a three-layer sandwich 16, the middle layer being the layer ofpadding 12. - The peripheral edges of said
sandwich pad 16 are turned over on to the free side 14.1 of the covering 14 and are sewn with a continuous through seam 17 (cf. Figs. 2, 3) so as to provide a continuous quadrilateral hem 16.1 in relief around the peripheral edges of said free side 14.1 of the covering 14. - Two opposite external corners 16.2 of said
sandwich pad 16 are cut obliquely to help it to fold along an imaginary diagonal line 16.3 joining these corners. - Attached by means of the
seam 17 to the outer side of two adjoining edges of said hem 16.1 that lie in the same half relative to the diagonal fold line 16.3, is a corresponding adhesive sealing strip 18.1, in PVC for example, its free side being adhesive. Attached by means of saidseam 17 to the outer side of the other two edges of the hem 16.1 is a corresponding sealing strip 18.2, in PVC for example, its free surface being nonadhesive but able to stick to the adhesive strip 18.1 when theenvelope 10 is folded over upon itself so as to close it and seal it. Advantageously, said strips 18.1, 18.2 are welded uninterruptedly (at 19.1, 19.2) to thebacking sheet 11 by hot welding or electrical welding, at least along saidseam 17. - In the middle of said
sandwich pad 16 is a microperforated punched circular imprint 16.4 for the selective manual removal of a corresponding discoidal portion 16.5 ofsaid pad 16, in order that a window 16.6 (Fig. 6) can be provided when necessary, as further described below. - For use, the
envelope 10 is placed with its side 14.1 uppermost and is impregnated by applying through the covering 14 a suitable sterilizing or anti-contaminating agent, for example an active liquid disinfectant. - The
padding 12 absorbs and uniformly imbibes the disinfectant, thereby providing an aseptic field. While thePVC backing sheet 11 prevents the escape of the liquid disinfectant, the nonwoven covering 14 traps the molecules of water released over time by the disinfectant within the Moltopren padding 12. This prolongs the action of the aseptic field created within theprotective envelope 10. - A medical appliance or a part of a medical appliance to be protected is then placed on top of said side 14.1 of the
envelope 10, arranging it on one half of this side bounded by the diagonal fold line 16.3 (Fig. 4). In Figures 4 to 6 the sketch of the appliance shows a connection R with two taps R1, to each of which a flexible pipe C is connected. - The
envelope 10 is then folded over upon itself along said diagonal fold line 16.3 until fully closed, as illustrated in Fig. 5, in the arrangement in which the two edges of the hem 16.1 furnished with the adhesive strip 18.1 are laid over the two respective edges of said hem 16.1 furnished with the nonadhesive strip 18.2. Light hand pressure on said superimposed edges seals theprotective envelope 10 along said peripheral hem 16.1 with the appliance R to be protected contained inside. The flexible pipes C of the appliance R emerge from the closedenvelope 10 through corresponding passages formed between the superimposed edges of the hem 16.1 and are held firmly in position by the adhesive strip 18.1 which adheres to their surface. - Among the advantageous results of the above-mentioned arrangement are the following:
- the
envelope 10 forms a closed chamber in which the appliance R is firmly accommodated and from which the applied liquid disinfectant or antiseptic cannot escape; - the sealing together of the superimposed edges of the hem 16.1 ensures not only that the liquid agent cannot escape but also that contaminating agents cannot infiltrate;
- furthermore, any contaminating agents that do get into said closed chamber, or into the
envelope 10 while still open, cannot penetrate between thesandwiched layers pad 16 because of the presence of the continuous welded joins 13, 15, nor between thebacking 11 and the sealing strips 18.1, 18.2 because of the continuous weld lines 19.1, 19.2. The only pathway for such agents is thepadding 12 and covering 14, and these are the very components that form the active field of asepsis protecting the appliance R; - the welding together of the components of the
pad 16 guarantees a continuous secure join and seal between thelayers - when the
envelope 10 is opened, the appliance R is kept in position by the adhesive strip 18.1 adhering to the flexible pipes C. - As illustrated in Fig. 6, the appliance R protected inside the
envelope 10 can if desired be hung up: it is simply necessary to remove, by hand, the central disc portion 16.5 of thepad 16 and insert into the hole a part with an eyelet O by which it can be hung from a suspended hook G. - Fig. 7 shows an alternative embodiment of the flexible protective envelope according to the model, here denoted as a whole by the
numeral 20. Theprotective envelope 20 differs from theenvelope 10 purely in its rectangular form and its smaller area. - The
envelope 20 is closed by folding it along its central longitudinal line (indicated by a dot-and-dash line 21) to bring together the longitudinal edges of itsperipheral hem 22. Attached to the outer side of one of said longitudinal edges of the hem is an adhesive sealing strip 23.1, of PVC for example, with an adhesive free side, while attached to the outer side of the other longitudinal edge is a nonadhesive sealing strip 23.2, of PVC for example, able to stick to the strip 23.1 to close and seal theenvelope 20. - In all other respects the previous description applies.
- Clearly, the effects of the present invention extend to models that provide equal utility by using the same innovative concept as expressed in the claims.
- Thus, for example, instead of mutually adhesive sealing strips it is possible to use magnetic sealing strips that hold together, separably, by magnetic attraction.
- The shape, dimensions and materials etc. can furthermore vary from those described and illustrated purely by way of non-restrictive illustration.
